Rebuilt Engine won't Run at Low RPM
I've been reading and lurking on this great site for the past 6 months and now I need some help.
We move to Texas hill country and brought with us a worn out Yamaha G14. When we got here the cart would only climb the shallowest hills in our neighborhood. Thanks to all of your recommendations we got a kit from Plowmans carts. What a great company!! Great knowledge and awesome customer service. That solved the hill problem but it smoked and stunk.
I rebuilt the engine. Block bored over .25 and valve job done by a machine shop. The engine now won't idle or run any slower than about 2500 RPM without dying. It will also backfire through the carb.
I've run a gravity feed fuel line to make sure it wasn't a fuel issue.
I've checked and rechecked the valves (.004)
I've cleaned the carb
The engine runs the same with or without the airbox hooked up
